yes, i have and i am there to answer questions, i lived there for several years. there is lots of info and as said before i have 2 books with detailed front elevations. they are from amsterdam but that does not matter as they are actually from the same era and built in the same way.
i thought up a way to avoid the 'squared' look and giving everybody the chance for somewhat more freedom and make it easier for people to join in later. if you agree i can work out what i mean, but i need a litle time for that.
